Applying Point Spectroscopy Data to Assess the Effects of Salinity and Sea Level Rise on Canopy Water Content of Juncus roemerianus

WithDonna Selch, Cara J. Abbott, Caiyun Zhang

Florida coasts have been threatened by the ongoing sea level rise. Sea level rise will modify the coastal hydrology such as tidal flushing and saltwater intrusion into coastal qualifiers, which in turn negatively affects productivity and community composition of freshwater systems. The projected damage of sea level rise presents a great challenge for conservation and management in Florida, especially in coastal regions. The spectroscopic data collected from an ASD spectroradiometer to quantify canopy water content of J. roemerianus under different treatments of water levels and salinity at a controlled environment. Assessing J. roemerianus responses to stressors such as salinity and water levels will aid in the monitoring and mapping of a changing coastal environment. The complex belowground matter typical of J. roemerianus meant that some roots would be left behind in the soil and that soil would cling to the roots; both factors would prevent accurate root biomass measurements.
